A pun joke in English language

Jim

A woman goes into a pharmacy, and walks down the
aisle. Halfway down the aisle, she calls to the
cashier,"Excuse me, do you have any batteries?"

Unable to hear, the man signals the woman with
his finger to come closer. He says, "Could you
just come this way?"

The woman laughs and tells the man, "If I
could cum that way I wouldn't need batteries."
